Abstract

In order to generate ultra short laser pulses, cavity losses have to be modulated at extremely high speed. The configuration proposed provides such type of modulation, achieving phase and amplitude modulation through one single electrooptical crystal. By varying the parameters of the electrical pulses applied to such crystal Q switching cavity dumping and mode locking are achie­ ved. The configuration is essentially made up of an electrooptical crystal (12), of a polarizer (8) and of at least two mirrors (10-12) which are totally reflective at both polarization states of the laser light and fits the frame of laser sources capable of generating short duration pulses or pulse trains.
